The 3VA1112-4EF36-0DC0: Breaking capacity is the headline spec on any MCCB, and this one delivers 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. The 415 V figure is the one you'll compare against your panel's prospective short-circuit current (PSCC) in a standard 400 V three-phase system. If your fault level at the breaker terminals is under 75.6 kA, this breaker holds. At 690 V the capacity drops to 11.9 kA — still enough for most 690 V industrial networks, but check your transformer impedance if you're close to that limit. The 240 V rating (121 kA) is typical for high-fault residential or light commercial subfeeds.
At 55 °C it derates to 120 A, at 60 °C to 117.5 A, at 65 °C to 115 A, and at 70 °C to 112.5 A.
The auxiliary switches can be wired into a PLC input to confirm breaker position.
